Answer:
14 newtons is the answer
Explanation:
because if they act in the same direction they are added together
For velocity vs Time graphs, the displacement of the object from 2 seconds to 6 seconds is 30 m.
<h3>What is displacement?</h3>
The displacement is the shortest distance travelled by the particle. It is the vector quantity which re[presents both the magnitude and direction.
In velocity time graphs, the displacement is the area under the curve of the graph on the x axis.
'
A line starts at (0, 2) and ends at (6, 8) in v-t graph
Displacement is equal to the area of a triangle and a rectangle formed under the line.
Area = 1/2 base x height + length x breadth
Area = 1/2 x 6x 6 + 6x2
Area = 18 +12
Area = 30 m
Thus, the displacement is 30 m.

The most common form of angina is stable angina.
C. stable
Answer:
This situation is possible.
Explanation:
It is said in the problem that one morning two trains are speeding up from opposite directions onto the bridge. It may seem from this statement that the trains are arriving at the same time. But this should be a wrong assumption.
Because it is only said in the problem that the trains are passing the bridge on same morning. No explicit timing is given.
So it may so happen that both the trains pass the narrow bridge on the same morning but at two difeerent times, making no collision with each other.
